4. FLEX M MODULES
The Flex M system comprises of a RF/CPU module and a power supply module with application specific
add-on cards in between the CPU module and power supply module.
During the operation of the receiver, the LED indicators will allow observation of the status of each of the
modules of the Flex M receiver. Refer to each of the sections below for specific information regarding
each of the modules. Be sure to reference the correct part number for each module type as some of the
modules have different versions.
4.1 RF/CPU MODULE – GEN 1
This section is applicable to the following RF/CPU module part number(s):
25-02-074-800E (900MHz Part 15)
25-02-074-801E (400MHz Legacy Communication)
25-02-074-807E (900MHz 1W) – No longer available
25-02-074-815E (900MHz 200mW) – No longer available
25-02-074-816E (433MHz Part 15)
25-02-074-818E (2.4GHz 50mW)
25-02-074-819E (2.4GHz 125mW)
25-02-074-821E (400-420MHz)
25-02-074-822E (410-430MHz)
NOTE: The high power RF/CPU Module 25-02-074-807E draws up to 1300mA of power when in use. It
requires high current power supply module 25-02-074-810E to perform properly.
The Flex RF/CPU Module is the main module that receives radio signals from a paired transmitter and
interprets those signals into the appropriate response for the attached I/O modules. There is one RF/CPU
module in the Flex M System.
